Is there data comparing the use of different pipettes and the associated forearm rotation during pipetting?
Ergonomic Technologies Corporation, an independent consulting firm specializing in workplace ergonomics, conducted a series of tests using traditional axial-designed pipettes and VistaLab Technologies’ new Ovation BioNatural Pipette. Electromyogram testing (EMG) was used to measure the activity of muscle groups and degrees of rotation during various pipetting tasks. (Electromyography (EMG) studies the function of individual nerves and muscles and includes measurement of nerve and muscle response to electrical stimulation and measurement of spontaneous muscle electrical activity) The testing revealed that the Ovation pipette showed a significant reduction in forearm rotation and wrist flexion during use when compared to other pipettes. The Ovation pipette’s shape and operating position reinforce ergonomically-correct pipetting by encouraging the user’s hand, wrist, and arm to assume the neutral postures near 45° pronation recommended by ergonomic experts.
